Answer:
No
Step-by-step explanation:
2√3 × 2√6
= 4√18
= 4√9*2
= 4( 2√2)
= 8√2
Just multiply the numbers under the radical together. √3 × √6 = √18. √18 can be written as √9*2, or 3√3.
√2 is irrational, so the answer will be irrational
Answer:
x = 9 + 6i or x = 9 - 6i
Step-by-step explanation:
x² - 18x + 117 = 0
Complete the square and solve:
(x - 9)² - 81 + 117 = 0
(x - 9)² + 36 = 0
(x - 9)² = -36
x - 9 = ±sqrt(-36)
x - 9 = ±sqrt(-1).sqrt(36)
i = imaginary number = sqrt(-1)
x - 9 = ±6i
x = 9 ± 6i
There are no real solutions, only imaginary ones
9 + 6i and 9 - 6i
